For me it has to be Tyson's entrance against Francois Botha in 1999, after his suspension against Holyfield.

Probably the most intimidating entrance ever, with the music being DMX- Intro. And the way Tyson doesnt go for these elaborate capes and what not, just sticks to the plain black towel thing which says "Be Real", class.

That one was good, but for the fact that I know that Tyson was no good, it isn't my favorite. The Spinks fight walk in was by far my favorite. It has to be the one on the HBO broadcast.
